A system for compressing information arranges unprocessed information into a plurality of data planes. The data planes are converted into a combined planar data output. The combined planar data output is created by regrouping data elements which make up the unprocessed information. The regrouping is ...

There are provided methods each of which is for efficiently compressing a test pattern to be applied to an IC for testing. The number of data changes &phgr; and a data entropy H of a pattern for each pin of an IC are obtained and then the test pattern is divided and the divided patterns are distribu ...

An adaptive vector quantization process and quantizer (VQ) using a clustering technique known as AFLC (adaptive fuzzy leader clustering) is disclosed. The quantizer, AFLC-VQ, has been designed to vector quantize wavelet decomposed sub images with optimal bit allocation. The high-resolution sub image ...

An image compression system includes a vectorizer and a hierarchical vector quantization table that outputs embedded code. The vectorizer converts an image into image vectors representing respective blocks of image pixels. The table provides computation-free transformation and compression of the ima ...

A signal coder is disclosed with improved compression of pictorial data that has been decomposed into plural subbands through a two-dimensional quadrature-mirror decomposition (102). In each of the higher frequency bands, the decomposed samples are quantized and then partitioned (106, 110, 114), in ...

A method for detecting radiated and reflected acoustic signals from an unwater source, wherein the acoustic signals are present in a random noise environment and form an output therewith. The method includes the steps of operating an entropy-based acoustic receiver to receive the output, calculating ...

A new method for real time implementation of rate-distortion optimized coding mode selection is disclosed that can be efficiently applied to H-263-compatible video codecs and other codecs of similar type. A normalized rate-distortion model is used to efficiently compute the rate and the distortion w ...

In any digital imaging system, the digital input signals must be converted to a visible image on some output material or medium. Because the range of this output medium is usually not the same as the input image range, care must be taken in converting the digital input signals into output signals. T ...
